Adding properties to point data

Hi - Is it possible to add additional information about a point besides just the name, such as a larger dialogue box with name, description, hyperlink, etc. based on this:

const czml = [
{
id: “document”,
name: “CZML Point”,
version: “1.0”,
},
{
id: “point 1”,
name: “test”,
position: {
cartographicDegrees: [0, 0, 0],
},
point: {
color: {
rgba: [12, 77, 162, 500],
},
outlineColor: {
rgba: [247, 148, 29, 255],
},
outlineWidth: 4,
pixelSize: 10,
},
},
